WAGON-BRAKE.

The Schedule referred to in these Letters Patent and parl: of the manie.

To all whom 'it may conce/rn Be it known that I, D. J. OWEN, of Springville, county of Snsqnehanna, State of Pennsylvania, have invented a new and improved Brake for Wagons; and I hereby declare the following to be a full, clear, and

exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawings, making a part of this specification, in which- Figure 1 is `a transverse vertical .section of a wagon, withmy improvedbrake attached, through line xx, iig. 2.

Figure 2 is a side elevation ofthe same.

Figure 3 is a top view of the same.

Similar letters of reference indicate corresponding parts.

My invention relates tov brakes for wagons; and

It consists in the combination of a wedge-formed rubber, with 'suitable devices for regulating the degree of pressure upon the wheels.

As the construction of none of the parts of a wagon is claimed, with the exception of the devices for regulating the brake-blocks, I enter into a minute description of those parts only which are directly connected with such devices, and of the devices themselves. A, in the drawings, are the wheels of the wagon.

B are the axles. O is the reach. D are the rear hounds. E are the forward hounds. l F is the tongue. G are the standards.

. H is the bed.

H is the ratchet.

I is the brake-beam or support, which is secured to the hounds, and to the reach, by ybeing notched in its lower surface, so as to fit thereon, and is held in position by means of screws or bolts, which pass through the beam and hounds atA their point of junction. vIn the upper surface of this beam a groove is formed, for the reception of the shaft K,' into which said shaft' is secured by eye-bolts passing through said beam.

K isa shaft, which is placed in vthe groove in the brake-beam or support, as above indicated, to the outer ends of which L L', are applied, which cranks receive'and carry upon their wrist-pins brakenectingrod O is secured.

O is the .connecting-rod, secured in any convenient manner to the arm N and to the hand-lever P.

P is the hand-lever, which communicates motion to the shaft, and the cranks thereon, by means'of connecting-rod O and vertical arm N. I

From the foregoing description, itis evident that a brake of this kind is self-acting, and that it requires no exertion of strength on the part of the driver 'to put the brake-blocks in position for action, or to withdraw y them. The rubber may be easily lowered by drawing I' the hand-lever back, to snit the plane descended or4 the load carried. The pressure had-may be very slight, or suiciently strong to bring the wheels to a dead-.- lock, by lowering the .rubber until its head restsl be# tween the support and the wheels.

I do not claim, as' my invention, a wedge-shaped brake-block orprubher; but

1. The combination of the fixed support Iwith the shaft K, cranks L L', and brake-blocks M, substantially as shown andv described.

2. The arrangement ohand-lever P, connectingrod 0,' and vertical arm N, with reference to the shaft K and crank L L', substantially as shown and described.

- In testimony whereof, I have signed my nameto this specification, in the presence of two subscribing wit- D. J. OWEN.
